    The molar masses of each element are:

    Ba = 137.3 g/mol

    N = 14 g/mol

    O = 16 g/mol

    Calculating the total mass by multiplying with number of moles:

    Ba = 137.3 g/mol * 1 mol = 137.3 g

    N = 14 g/mol * 2 mol = 28 g

    O = 16 g/mol * 6 mol = 96 g

    Total 261.3g

    Ba: 137.3/261.3 = 52.55%

    N: 96/261.3 = 36.73%

    O: 24/261.3 = 10.72%

    Answer:

    52.55% Ba, 10.72% N, 36.73% O
